oars 3-19-75 F. P. c?DO 2 6 - d 1.0 SCOPE 1.1 This specification contains parameters for those essential and nonessential variables applicable to velding performed in accord-ance with the ASE Boiler and Pressure Vessel Code, which are shop standards and, therefore, not variables for velding at Dravo Pipe Fabrication Division. This specification is incorporated into Welding Procedure Specifications (WPS's) by reference in each k'PS.

Some parameters that vary only by process or veldsent material are listed here and referenced in the WPS in sufficient detail to

- conply with Code requirenents.

1.2 The parameters for nonessential variables contained in this speci-fication may be modified to meet special customer requirements by the generation of contract addenda to this specification.

1.3 The parameters for essential variables contained in this specifi-cation are qualified by the PQR(s) referenced in each WPS.

1.4 This procedure does not control the inspection requirements or the

~

acceptance criteria for velds. Inspection and acceptance levels shall be as shown in Dravo Standard Shop ?rocedures.

1.5 This revision complies with the requirements of the ASE IX (and addenda) applicable on the date of issue of this procedure. This procedure shall be reviewed for compliance with later editions and addenda, and revised only as required.

2.3 QUALITICATIONS 2.1 k?S's, velders, and welding operators shall be qualified per the ASME Boiler and Pressure Vessel Code, Sections III and II, unless otherwise specified.

WPS's must be used exactiv as written, with the exception of purge 2.2 d requirements (See 10.2). Any desired changes should be referred to Drave Welding Engineering. Changes may require revision of a WPS, qualification.of a new WPS, or selection of a different WPS.

3.0 kTLDING PROCESSIS 3.1 The velding process (es) (including type-manual, semiautomatic or machina) shall be as specified in the applicable k?S.

6.0 TILLIR MATERIALS 6.1 Filler materials specified in each WPS are selected with considera-l tion of the co=patibility of the base and filler metals from the l

standpoint of metallurgical properties postveld heat treatment

! design and service requirements, and mechanical properties.

6.2 Consumable inserts, when used, shall be specified in the WPS and shall be s1=ilar in co=mosition to the filler material to be used for the balance of the veld, unless otherwise specified.
